Whey you say nothing is working, what exactly are you referring to? Macros?
Calculations?

Make sure Calculations are automatic.
Tools-Options-Calculations-Automatic.
If it is macros that don't work. Check to see if your opening macro is
disabling events. If it is, then you'll need to renable them.

I have a strange problem with a workbook. Someone opened it, clicked on
"activating macro's", the workbook openend with the start-up macro
(showing a userform), but
after that nothing worked. Except one thing: a button with a link to a
website.

He was using Excel 2000. Can anyone explain this situation? And: what to
do about it?
